A schematic (or technical schematic, technical manual) is a guide to the workings of a starship or device.
In 2268, Commander Montgomery Scott was excited to be confined to quarters as punishment for starting a fight with the Klingons, because it would give him a chance to catch up on reading his technical journals. (TOS: "The Trouble with Tribbles"")
There have been several technical manuals which have actually been published. The following is a list:
- Star Fleet Technical Manual
- Star Trek: The Next Generation Technical Manual
- Star Trek: The Next Generation Interactive Technical Manual
- Star Trek: Deep Space Nine Technical Manual
